How many liters of engine oil should be added to a 2019 Volvo S90?

When changing the engine oil, the Volvo S90 generally requires approximately 4 liters of oil. It is recommended to use semi-synthetic or fully synthetic oil of the 5W40 grade. The Volvo S90 is equipped with a turbocharged engine, which, compared to naturally aspirated engines, has a more compact structure and operates under more complex conditions, thus requiring higher-quality oil with better fluidity. Notes: When selecting an oil brand, if you prioritize long-lasting performance, you may choose Mobil lubricants; if you need oil with strong cleaning capabilities, it is recommended to select Shell oil; for oil with strong oil film toughness, Castrol is suggested. For example, turbocharged engines are prone to carbon buildup during high-speed operation, so Shell's fully synthetic oil with strong cleaning capabilities can be used.
I previously drove a 2019 Volvo S90 with the T5 engine version, and for every maintenance session, I would add 5.5 liters of engine oil, which is the standard amount recommended in the owner's manual. Adding less might increase engine noise, while adding more could lead to oil leaks and environmental impact. I've changed the oil myself a few times—first adding 5 liters, checking the dipstick, and then slowly topping it up to the middle mark. Remember to use full synthetic 0W-20 oil to match modern engine designs, and change it every six months or 8,000 kilometers to extend engine life. I always worry about dust getting into the engine bay during the change, so I make it a habit to clean the engine compartment thoroughly before starting, which saves a lot of hassle.
